Running 15.2.1 just wondering what causes high # of unscheduled symbols. not just ungrouped but unscheduled i notice i have a high amount of those even though i have gps sync + decent modulations, and everyone on 15.2.1
I believe unscheduled means there was no traffic to pass in the downlink. These are slots that were empty because there was no demand.
To some of the other points they could be empty in the downlink because the uplink has been choked off with too few control/contention slots, but I think that would be a rare case and would almost require a huge misconfiguration. (i.e. 85% downlink ratio and only 1 reserved control/contention slot.)
